Greetings all. My Marantz LD player has been making a loud whining/screeching sound when first starting to play a disc. During the noise, the picture sometimes gets distorted a bit. If I jump several chapters ahead, the noise stops. It happens on nearly every disc I try. Unfortunately, laserdisc was never very popular in my town, so none of the shops want to look at it. A couple have said they will, but let me know that they may have to order some tools (at my cost, of course) to do it. I'm hoping someone here may have a hint or suggestion for me. I'm willing to open it up and try some things. I don't know the model number of the top of my head, but it has two-sided playback, AC-3 RF out and optical audio out. Thanks in advance!
